To all whom it may concern:

Be it known that I, CLAns RYDEN, a citi zen of the United States, residing at Providence, in the county of Providence and State of Rhode Island, have invented certain new and useful Improvements in finding-Machines, of which the following is a specification.

My invention relates to winding machines for winding cops or bobbins and particularly to that class of machines in which an oscillating thread-guide bears on the conical surface of the winding and advances progressively along the axis of the winding spindle.

My invention consists of improvements in the thread-guide mechanism and has for its object to provide means for effecting a smooth, even feeding movement of the guide along its traverse rod and for applying pressure to the guide to maintain its delivering eye in constant contact with the winding.

The essential features of the invention are fully described in the following specication, illustrated by the accompanying drawings, in which Figure 1 is a front elevation of the main portion of a winding machine showing my improved thread-guide mechanism applied thereto; Fig. 2, an enlarged end elevation of the same; Fig. 3, an enlarged plan view of. the threadguide mechanism; Fig. 41, an enlarged sectional view of the guide-feeding mechanism, taken on the line {U,J} of ig. 8; Fig. 5, an end elevation of the thread-guide mechanism, with the supporting bracket and bobbin mandrel shown in section; Fig. 6, an isometric projection of the thread-guide slide or runner; Fig. 7, a detail view of the lever T.

The machine in general is of well known type of construction and comprises the main frame A carrying bearings for the horizontal shaft Z) and 0. The shaft 5 overhangs the front of the frame and serves as a winding spindle for carrying the tube or bobbin B on which the yarn is wound. The shaft 0 is arranged below the shaft and carries a cam C adapted to impart a reciprocatory movement to the thread-guide G. The two shafts 72 and 0 are connected to rotate togcther by a belt or gearing, not here shown,

7 and usually means are provided to regulate their relative speeds to control the laying of the coils of winding.

Fastened to the front of the frame A is an overhanging bracket D which projects outward opposite to and parallel with the winding spindle. Preferably the bracket D is mounted on the end of the cam shaft 0 and bolted to the frame at J and (2. Secured in bearings d and (Z at either end of the bracket D is a horizontal traversebar or rod E on which the thread-guide G and its correlated mechanism is mounted.

The bracket D has an extension 03 reaching in toward the cam C and formed with a bearing for the pivoted lever or rockerarm F. The lower arm f of the lever F extends downward adjacent the cam C and at its end carries a stud or roll f whichengages the groove in the periphery of the cam. The upper arm f of the lever F is connected by a link 72, to a sleeve H which slides on the traverse-rod E and is traversed back and forth by the movement of the.

means comprise a friction progressionwheel I adapted to be rotated by contact with the winding and acting to feed the guide progressively along the winding spindle during the winding of the bobbin.

The guide-advancing mechanism is shown in detail in Fig. 4 and consists of the following arrangement :Adapted to slide on the threaded sleeve H is a bushing J having a flange 7' to which the progression or contact wheel I is secured. Surrounding the bushing J is a cylindrical thimble or casing K which incloses a pawl 70. The pawl 7c is pivoted at 70 in a slot in the bushing J and one arm 70 extends upward through an opening in the casing K. The

a bifurcated member L formed with two legs Z, Z, having their ends curled up at Z, Z to surround the sleeve H, and adapted to straddle the bushing J. The member L acts as a guiding runner and reaches down to the bracket D with its lower edge adapted to slide in a longitudinal slot (Z formed in the upper horizontal arm of said bracket, see Fig. 5. The thread-guide Gr consists of a slotted button 9 held in the end of the arm g which is mounted to oscillate on the traverse-rod E. The am g is preferably constructed of sheet metal shaped like the letter A and having the legs 9 and swiveled on the sleeve H. As shown in ,Figs.

'3 and 5 the extremities of the legs 9 and 9 have ears 9 and g bent down at right angles to the main portions and pierced with holes in which are secured the bushings g and {1 The inner ends of the bushings g and g abut the ends of the portions Z, Z on the runner L and the three elements,

guide Gr, bushing J and runner L, are thus assembled to move in conjunction. Fastened at m on the runner L is a flatspring M which reaches up and bears on the end of the leg 9 of the thread-guide arm 9, see

- Figs. 1, 3 and 5. As illustrated in Fig. 5,

the spring M acts to control the swinging movement of the arm 9. When the arm g is in theposition shown by full lines the pressure of the spring M tends to rock the arm to move the guide 9 down toward the axis of the winding spindle b. The cop or bobbin is wound on the tube B in the form indicated by the dot-and-dash lines in Fig.

, l, and the thread-guide g traverses up and down the incline of the conical nose end of the bobbin. The arm g oscillates up and down on the axis of traverse-bar E to allow this movement of the guide. The spring M pressing on the end of the guidearm g keeps the guide 9 constantly in contact with the conical surface of the bobbin and the coils of yarn are thus disposed regularly and systematically on the nose of the bobbin. In piecing-up or repairing breaks in'the yarn it is more convenient to move the guide away from the bobbin in order to locate the broken end. When this is required the arm 9 is swung up to the position shown by dotted lines in Fig. 5, and the spring M will then engage the fiat side of the leg 9 of the guide-arm and maintain the guide raised away from the bobbin until the machine is ready to operate again. The arm 9 is then simply pressed downward by the operator until the guide 9 bears on the bobbin and the spring hf exerts a yielding pressure on the arm to maintain the guide in constant contact with the windmg.

The runner L has a slot Z running longitudinally of its lower edge and at one end the metal is bent up to form the lug Z see Fig. 6, which abuts the side of the spring M and serves to hold the latter against side play. The greater portion of the metal cut away from the slot Z is curled up at Z to form a projection adapted to coact with the stopping mechanism of the machine to cause the arrest of operation of the latter when the bobbin is completed. The ar rangement and method of operation of the stopping device is as follows:

Referring to Fig. 2, the operation of the machine is controlled through a starting handle N. The handle N is mounted on a rocker-shaft n which is connected at the rear end of the machine to the clutchor beltshifting devices which control the driving mechanism. These devices may be of any usual construction and are not here shown or described since they are familiar to those versed in the art and form no part of the present invention. The handle N has a downwardly extending arm 93. formed at its end with a detent shoulder n This shoulder engages a corresponding shoulder 0 on a lever O which is pivoted at (Z on the frame of the machine. The rocker-shaft n is operated by a spring or other suitable means, not here shown, to move the handle N in the direction indicated by the arrow 2 and such movement disengages the driving mechanism to arrest the operation of the machine. An arm n on the handle N carries a brake-shoe p which is adapted to bear on thedisk P on the spindle b to brake the latter after the driving devices are disconnected. When the machine is operating, the handle N is held in the position illustrated in Fig. 2 by the engagement of the detent shoulders of and 0. By raising the lever O the detents are released to allow the handle N and shaft 12. to move to stop the machine as just described. The lever O is moved by the following described instrumentalities: Pivoted at 1" on the lower end of the lever O is a trip-lever R reach ing down toward the camshaft c. Mounted on the end of the cam-shaft and rotating therewith is a wheel or disk S formed with teeth 8 on its periphery. The wheel S rotates in the direction indicated by the arrow y and when the lever B is raised to engage the teeth 8, as shown by dash lines in Fig. 2, the turning of the wheel acts to force the lever outward to raise the lever O. This disengages the detents n and 0 and releases the handle N. Normally the trip-lever R is maintained out of range of the wheel S through gravity and its end rests on an offset toe t at the end of the lever T, see Figs. 2 and 7. The lever T is secured at its opposite end to a rod 6, see Figs. 1 and 2, which rocks in bearings in the frame D. Adjustably secured to the rod t by the screw u is an arm U reaching up in the path of the runner L. The upper end of the arm U is twisted or bent to form a beveled surface adapted to be engaged by the rounded projection Z on the runner L. The arm U is adjusted along the rod t according to the length of bobbin to be wound on the spindle Z) and as the guide G feeds along sleeve H the runner L eventually reaches a point opposite the arm. As the guide G moves outward in its traverse the projection Z engages the beveled face of the arm and rocks the latter outward to turn the rod 16 and lift the lever T to engage the lever B with the wheel S.

As before stated, the bracket D serves as a support for the traverserod E and adjacent the bearings (Z and (Z are coiled springs 12, c which act as buffers for the ends of the sleeve H as the latter reciprocates back and forth on the rod. The bracket D also carries an outboard bearing for the end of the spindle b to support the overhanging portion of the latter. This consists of a hinged arm W, see Fig. 2, which has a conical bore adapted to fit the tapered end of the spindle. A flat spring 10 is fastened to the bracket at w and its end bears on the flat edge of the arm, see Fig. 1, to hold the latter in position. The arm W can be swung away from the end of the spindle to allow the bobbin tube to be placed in position and for dotting the bobbin when the latter is completed.

The operation of the whole machine is as follows: The bobbin tube B is placed on the spindle b and the bearing arm W snapped over the end of the latter. The guide G is next adjusted to a position at the inner end of the traverserod E by releasing the pawl Z: and sliding the bushing J along the sleeve H. The thread-guide button 9 will then bear on the conical face B of the tube B with the spring M tending to maintain it in contact therewith. The throw of the cam C is arranged to give a traverse to the thread-guide equal in length to the tapered portion B of the tube B and as the guide reciprocates back and forth, under influence of the movement of the lever F, a layer of yarn is Wound on the conical face of the tube. As this layer of yarn is completed the progression wheel I traversing back toward the point of greatest diameter of the winding contacts with the surface of the yarn and a slight-rotativeimpetus is im parted to the wheel. This turns the bushing J and, as the pawl 7c is in engagement with the screw-threads on the sleeve H the bushing and its correlated parts are advanced along the sleeve. The feeding of the thread-guide along the winding spindle is continued intermittently and the layers of winding advance progressively outward along the bobbin tube. The bobbin thus grows by longitudinal extension and when completed is of a familiar form having a cylindrical body and conical delivery end or nose, as illustrated by dotanddash lines in Fig. 1.

As previously explained the arm U can be adjusted in position along the rod if so that it is engaged by the slide L at a predetermined point in the winding, according to the length of bobbin required. When this engagement takes place the arm U is tilted to rock the rod t and lift the lever T to operate the stopping mechanism of the machine as before described.

The novel and essential feature of my invention which shows improvement over previous devices consists of the arrangement of the slide or runner L which guides the movement of the thread-guide and guideadvancing devices, and through which pressure is applied to the guide tomaintain the latter in contact with the winding. In previously used devices of this type the threadguide arm which supports the guide button has been arranged to straddle the nut or bushing on which the contact wheel is mounted. With such an arrangement there must necessarily be friction between the two elements and this prevents a free and easy rotation of the progression wheel. The wheel I must be operated from a very slight contact with the winding, as otherwise the pressure against the bobbin will chafe and abrade the yarn. To prevent hindrance to the turning of the wheel I interpose the bearings, Z, Z of the runner L between the ends of the bushing J and the bushings g and g of the guide-arm g. The arm 9 has a constant oscillatory movement as the guide rides up and down the incline of the winding surface and in previously known devices, where the arm is arranged to bear against the ends of the nut or bushing J, this movement has a tendency to influence the turning movement of the contact wheel. In some cases the guide-arm will bind the wheel bushing and prevent its turning and such interference prevents the proper feeding of the tread-guide. If the guide does not move regularly and evenly along the traverse-bar the layers of winding will not be properly formed and the bobbin will be imperfect. In other words, where the feeding of the guide is hindered the layers of yarn will be unevenly spaced and the surface of the bobbin will have hollows and ridges. A bobbin malformed in such a way will not deliver the yarn freely in unwinding and hence cannot be used to advantage in the transferring processes for which it is intended. In my new device the slide L is held from'turning on the traversebar by the guiding groove in the bracket D and hence its bearings on the sleeve H are fixed rotatively in relation to the bushing J so that the latter is not cramped or held from free rotation. A further improvement of my arrangement is the means on the runner L for applying pressure to the guide. Heretofore, it has been necessary to provide a bearing-barpivoted on the traverse-bar and arranged to bear on the guide-arm through the use of springs or weights. The spring M takes the place of such a pressure device and besides being exceedingly simple in arrangement and of cheap construction it also acts automatically to hold the guide away from the'winding in piecing up and therefore provides for greater convenience in operating the machine.

It will be evident that various modifications might be made in the structure and arrangement of my new device without departing from the spirit or scope of the invention,
